User's Manual
CAUTION: It is very important that you read this information regarding the possible
effects of Electromagnetic Interference on your power chair.
Powered wheelchairs and motorized scooters may be susceptible to electromagnetic
interference (EMI), which is interfering electromagnetic energy (EM) emitted from sources
such as radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios,
and cellular phones. The interference (from radio wave sources) can cause the power
chair to release its brakes, move by itself, or move in unintended directions. It can also
permanently damage the power chair control system. The intensity of the interfering
EM energy can be measured in volts per meter (V/m). Each power chair can resist EMI
up to a certain intensity. This is called its "immunity level." The higher the immunity level,
the greater the protection will be. At this time, current technology is capable of achieving
at least a 20 V/m immunity level, which would provide useful protection from the more
common sources of radiated EMI. The immunity level of this product is 20 (V/m).
There are a number of sources of relatively intense electromagnetic fields in the everyday
environment. Some of these sources are obvious and easy to avoid. Others are not
apparent and exposure is unavoidable. However, we believe that by following the warnings
listed below, your risk to EMI will be minimized.
Electromagnetic Interference and Warnings:
The sources of radiated EMI can be broadly classified into three types:
1.Hand-held portable transceivers (transmitters-receivers) with the antenna mounted
directly on the transmitting unit. Examples include: citizens band (CB) radios,
"walkie talkie," security, fire, and police transceivers, cellular telephones, and other
personal communication devices.
Some cellular telephones and similar devices transmit signals while
they are ON, even when not being used.
2.Medium-range mobile transceivers, such as those used in police cars, fire trucks,
ambulances, and taxis. These usually have the antenna mounted on the outside of
the vehicle.
User's Manual
3.Long-range transmitters and transceivers such as commercial broadcast transmitters
(radio and TV broadcast antenna towers) and amateur (HAM) radios.
Other types of hand-held devices, such as cordless phones, laptop
computers, AM/FM radios, TV sets, CD players, and cassette players,
and small appliances, such as electric shavers and hair dryers, so far
as we know, are not likely to cause EMI problems to your power chair.
Power Chair Electromagnetic Interference:
Because EM energy rapidly becomes more intense as one moves closer to the transmitting
antenna (source), the EM fields from hand-held radio wave sources (transceivers) are of
special concern. It is possible to unintentionally bring high levels of EM energy very close
to the power chair control system while using these devices. This can affect power chair
movement and braking. Therefore, the warnings listed below are recommended to prevent
possible interference with the control system of the power chair.
Electromagnetic Interference and Warnings:
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur
radio (HAM) transmitters, two-way radios, and cellular phones can affect the power chair.
Following the warnings listed below should reduce the chance of unintended brake release
or power chair movement, which could result in serious injury.
1.Do not operate hand-held transceivers (transmitters-receivers), such as citizens band
(CB) radios, or turn ON personal communication devices, such as cellular phones,
while the power chair is turned ON;
2.Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming
close to them;
3.If unintended movement or brake release occurs, turn the power chair OFF as soon
as it is safe;
4.Be aware that adding accessories or components, or modifying the power chair, may
make it more susceptible to EMI; and
5.Report all incidents of unintended movement or brake release to the distributor listed
on the inside front cover of this manual. Note whether there is a source of EMI nearby.
Important Information
1.20 volts per meter (V/m) is a generally achievable and useful immunity level against EMI
(as of May 1994). The higher the level, the greater the protection.
2.The immunity level of this product is 20 (V/m).

User's Manual
Taking care of your power chair will keep it in top-notch condition. It is recommended
that you have your dealer provide preventative maintenance service of your power chair
on a regularly basis. Here are a few maintenance guidelines:
If your power chair is dirty, use a damp or lightly soapy cloth to wipe it down. Do not use
running water to wash or rinse the power chair in order to protect the electrical parts.
Polish with an automotive liquid polish.
The seat material used by C.T.M. is a product of high quality and will remain in good
condition for many years if treated responsibly. Using a damp cloth helps clean the
upholstery greatly. Please note that using the power chair outdoors can lead to sun
damage of the upholstery material. Since this is a normal wear and tear condition, it is
not covered under the warranty.
A damp cloth with mild soapsuds should only be used to clean the seat belts. Wipe the
seat belts gently removing any debris on it. Do not use any chemical products to clean
the seat belts as the fabric will be weakened.
An authorized dealer should handle all maintenance and repair of your
power chair that is associated with electronics, batteries, motor parts,
and tires. Here are the guidelines that can be followed by the authorized
FLAT SPOT (for solid tires only):
During the storage period, a flat spot may occur on solid tires. Weather conditions and
storage period could determine the condition of flat spots. By driving the power chair
20 to 30 minutes, flat spots can be eliminated.
User's Manual
TIRE PRESSURE (for air-filled tires only):
The condition of the tires and maintenance of the specified tire pressures not only
influence tire life but also road safety to a very considerable extent. Incorrect pressures
are often a cause of tire problems and could result in an accident. The recommended
tire pressure is 35 lbs.
Inspect the tires frequently for any signs of damage, unusual wear and sufficient tread
depth. Thread depth should not be allowed to drop below 1 mm.
Verify the battery terminals and all plug connectors are secured and firmly attached. If
the battery terminals are corroded, please contact your dealer for replacement.
Check that all hardware exist and are securely fastened. Replace any missing hardware
by contacting your dealer for information of parts.
